Vegetation Departure

Vegetation Departure (VDep) indicates how different current vegetation on a landscape is from estimated historical conditions. VDep is based on changes to vegetation composition, structural stage, and canopy closure using methods originally described in the Interagency Fire Regime Condition Class Guidebook, but is not identical to those methods. LANDFIRE (LF) VDep is based only on departure of current vegetation conditions from reference vegetation conditions, whereas the Guidebook approach includes departure of current fire regimes from those of the reference period.

VDep, a landscape metric, is scale dependent. Every pixel in a unique biophysical settings (BpS) in a summary unit has the same VDep value. These large landscape values may not represent smaller areas within a summary unit.

The VDep metric ranges from 0 - 100 and is based on 4 factors. These inputs are held constant within a single version of LF, but can be different across LF versions, which directly impacts VDep comparability across versions. VDep can be compared across versions but caution is advised.

VDep is part of the LF Remap release of Fire Regime products.
